Questions
- Which postulate can be used to prove that two triangles are congruent if two sides and the included angle are congruent?
- Which of the following are valid reasons for proving two triangles are similar?
- If two triangles have all three pairs of corresponding sides congruent, the triangles are congruent.
- What is the name of the property that states if segment AB is congruent to segment CD, then segment CD is congruent to segment AB?
- Which of the following statements is true about vertical angles?
- Which of the following statements are always true about parallelograms?
- If two triangles are similar, then their corresponding angles are congruent.
- What is the missing reason in this proof? If angle A is congruent to angle B and angle B is congruent to angle C, then angle A is congruent to angle C by the ____ property.
